AI Technical Summary

⚠Technical Problem

During the pressure test, the magnetic core tube is easily deformed and damaged due to excessive clamping force, which will affect subsequent assembly.

⚗Method used

A magnetic core tube withstand pressure test structure is designed, including a base, an oil nozzle, a connecting block, and a pressure block. The magnetic core tube is floated in the test space by hydraulic oil to conduct the test, avoiding direct contact and compression.

🎯Benefits of technology

This effectively prevents the magnetic core tube from deforming and being damaged during testing, ensuring test quality and facilitating subsequent assembly.
